Ten subjects passing screening will take for 2 weeks between dinner and bedtime in a blinded and balanced order: 1. Eight ounces of cherry juice standardized to its proanthocyanidin content in the morning and 8 ounces of cherry juice standardized to its procyanidin content 1-2 hours before bedtime for 14 days; 2. A similar amount of placebo juice with the same timing for the cross-over. There will be a 2-week washout between each of the treatment periods. Subjects will be scheduled for two overnight PSGs, one at the end of each two-week treatment period. On the morning following each test the insomnia severity index and other questionnaires will be repeated. The order of the placebo juice and cherry juice will be random and balanced.

Compare the Insomnia Severity Index, a validated questionnaire, in participants with insomnia on a night at the end of 2 weeks taking: 1. Eight ounces of cherry juice standardized to its proanthocyanidin content in the morning, and 1-2 hours before bedtime; 2. Eight ounces of an identical appearing placebo in the morning and 1-2 hours before bedtime.

Compare five different sleep quality scales with insomnia on a night at the end of 2 weeks taking: 1. An 8-ounce glass of cherry juice standardized to its proanthocyanidin content in the morning and 1-2 hours before bedtime; 2. an 8- ounce glass of an identical appearing placebo in the morning and 1-2 hours before bedtime.
